Problem with Javascript not inputting value into hidden fields

Answer 1

+1 A:

This actually works as it alerts the correct value:

<html>
<head>
    <title>Test</title>
</head>
<body onload="document.getElementById('ClientDateTime').value='hello world'; alert(document.getElementById('ClientDateTime').value);">

<input type="hidden" name="ClientDateTime" id="ClientDateTime" value="" />

</body>
</html>

Yes, that alerts the correct value, but the hidden field's value is still blank. So when I got to submit this form, there is nothing in there.

Maybe just because the source code isnt' changed that it's still really in there? I'm going to run a test and see...

Yep, it was actually changed, just not in the View Source. Thank you!
